Specification of Letters Patent.

Applica'tion'filed August 26, 1916, Serial No. 117,082. Renewed June 17,1918. Serial No. 240,530.

To all whom it may concern:

Be it known that I, Jnsrnn BLACKBURN, a citizen of the United States,and resident of Webster Groves, Saint Louis county, Missouri, haveinvented certain new and useful Improvements in Cable-Hangers of whichthe following is a specification containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to certain new and useful improvements in cablehangers or holders wherein a. supporting device is-provided for a cable,and further-provided with means in the form of hooks for suspension froma messenger wire.

A further'object is to" provide a hanger formed from a single piece ofelastic wire by suitable automatic machinery, said hanger being providedwith a maximum contact surface when applied to the messenger to preventcreeping or sliding of the hanger over the messenger wire when the cableis being applied to the hangers.

A still further object is to construct a hanger which is used not onlyin the installation of new work, but may be applied for the support ofexisting cables, said hanger when in use having a series of supportingsurfaces for the cable, so as to distribute the weight of the cable onmore than one point.

With the above purposes in view, my in vention consists in certain noveldetails of the construction and arrangement of parts which will behereinafter more fully described, pointed out in my claims andillustrated by the accompanying drawings, in which:

Figure 1 is a perspective view of my improved hanger or holder appliedto a messenger or supporting wire, the cable being shown in dottedlines;

Fig. 2 is a perspective view of my hanger being applied to a messengerwire, illustrating the method of applying the same; and

Fig. 3 is an end view looking in the direction of the arrow in Fig. 1.

Referring by numerals to the accompanying drawings:

l designates the body portion of the hanger, which comprises twosubstantially U-shaped portions (in plan view) 5 and 6, which arearranged side by side, as illustrated, said portions in end elevationbeing upwardly curved so as to provide a rounded or curved seat for thecable.

Formed integral with the U-shaped portion 5 is a branch arm 7, andformed integral with the U-shaped portion 6 is a branch arm 8, said arms7 and 8 being curved in opposite directions.

The arm 7 is provided, near itsterminal portion, with a bent portion 9,a substantially straight semi-elastic portion 10, and with a hookedportion 11, these portions just referred to acting as contact,surfaceswith the messenger or supporting wire when the same is applied for use.

The branch arm 8 is provided with an abruptly bent portion 12, whichterminates in a substantially horizontal portion 13 and a hooked portion14.

In the application of my improved holder or hanger the hooked portion 11is first applied beneath the messenger or supporting wire, with thesubstantially straight portion 10 resting on the top surface of the messenger wire. When in this position the branch arm 8 is in front of themessenger wire, as illustrated in Fig. 2, and a clownward force isapplied until the hooked portion 14 passes beneath and in the rear ofthe messenger and is then engaged with it. The substantially horizontalportion 13 of the hooked portion 14: holds the hanger in position foruse on the messenger.

It will be observed that my improved hanger has three contacts orgripping surfaces, namely, the bent portion 9, the substantiallystraight portion 10 and the hooked portion 11, thus providing sufilcientcontact surface to prevent the hanger or holder from movement on themessenger wire.

It will further be observed that my improved hanger has three supportingsurfaces for the cable, thus distributing the wei ht of the cable tothree points.

I-faving thus described my invention, what I claim as new therein anddesire to secure 2y Letters Patent of the United States thereor, 1s:

1. A cable hanger, comprising a body portion formed of substantiallyU-shapcd portions in plan and curved in end elevation, arms formedintegral with said substantially U-shaped portions and curved inopposite directions, one of said arms being provided with an inwardlybent portion, a substantially straight portion adapted to extend overamess'enger wire and a hooked portion adapted to extend beneath amessenger wire, and the other arm provided with a hooked portion adaptedto engage the messenger wire.

2. A cable hanger, provided with a body portion on which a cable isadapted to rest, oppositely curved arms formed integral with said bodyportion, one of said arms being provided with a bent portion adapted toengage a messenger wire on its side, a substan tially straight portionoi greater length than the'diameter of the messenger wire to which thehanger is applied arranged diagonally to the longitudinal axis of themessenger Wire and adapted to engage it on its top surface and a hookedportion formed integral with said substantially straight portion adaptedto-engage amessenger Wire on its lower'surface, and theother of saidarmshaving formed integrally therewith a hooked --portion-adapted to engagewith the messenger Wire.

3. A cable hanger, provided with a body portion, on which a cable isadapted to "rest and be supported, arms formed integral With 'saidbodyportion, one of said arms being provided with a substantially straightportion, adapted to rest-on the top of a messenger and disposeddiagonally of the messenger, said substantially straight portion beingprovided with a hook adapted to rest beneath the messenger, a bendinterj aeent the armx and the substantially "straight portion engagingthe messenger in opposition to said hook, the otherof said armsbeingprovided with a substantially horizontal portion adapted to lie beneathand transversely of the messengerand held thereupon by the resiliency ofthe hanger, said :sub-

'stantially horizontal portion being provided JASPER BLACK-BURN.
